in response to your radio talk today (2012-08-03), I would just like to comment, that ELECTRO-MAGNETIC FIELDS & RADIATION (EMF/EMR) have much more IMPACT on all living organisms (Human, Animal and Plant, but also DNA, Viruses and Fungi and Germs) as is currently known or taken for granted.

Given the FACT, that EMFs are also responsible for many PHYSIOLOGICAL CHANGES in the body, which are causing PSYCHOLOGICAL EFFECTS, like ADD/ADHD, Bipolar and many others, to start off with.

WIRELESS COMMUNICATION is doing us a big disfavour and is complicating the whole setup even further. This includes Cellphones & its Towers, W-LAN/Wi-Fi/WiMAX and others, inclusive of DECT and TETRA phones - and it is just getting worse.
We will see the CANCER RATE in Stellenbosch tripple in the not to distant future, as more and more people are switching in to their WIRELESS NETWORK (giving "FREE" Internet - which is not so FREE if you have to pay with your HEALTH and WELL-BEING in the end!).
